What Are the Symptoms of Low Blood Sugar?

The symptoms of low blood sugar include confusion, hunger, irritability, headaches and fatigue, according to the American Diabetes Association. The medical term for low blood sugar is hypoglycemia.

Hypoglycemia symptoms tend to come on suddenly, states the American Diabetes Association. Additional symptoms include shaking, nervousness, rapid heartbeat, dizziness and sleepiness. Some people with severe hypoglycemia have seizures or lose consciousness. Low blood sugar also causes sweating, chills, lack of coordination, anger and impatience.

Someone with low blood sugar should eat 15 to 20 grams of simple carbohydrates, recommends the American Diabetes Association. There are 15 to 20 grams of simple carbohydrates in 2 tablespoons of raisins, 1 tablespoon of sugar or 8 ounces of skim milk. Jellybeans and hard candies are also useful for increasing blood sugar quickly. Someone with hypoglycemia should consult the nutrition label on the package to determine how many candies to eat to get 15 to 20 grams of carbohydrates. People who are prone to hypoglycemia should consider keeping glucose tablets on hand for fast treatment of hypoglycemia.

Type 1 diabetics should keep glucagon kits in their homes in case of hypoglycemia, recommends the Joslin Diabetes Center. If a Type 1 diabetic passes out due to low blood sugar, a family member should inject glucagon into the diabetic's skin. Anyone who experiences low blood sugar and does not know the cause should seek advice from a medical professional.
